Abstract: According to one embodiment, a method of increasing a perceived resolution of a display includes directing light at a optical dithering element and repeatedly transitioning the optical dithering element from a first position to a second position and then back to the first position such that the mirror alternately reflects light to a first position on the display and then to a second position on the display. Each transition of the mirror includes controlling any overshoot or ringing in the position of the optical dithering element by providing a predetermined drive signal to the optical dithering element to smoothly accelerate and decelerate the element during the traverse between the first and second positions.

Abstract: Selective encapsulation of a micro electro-mechanical pressure sensor provides for protection of the wire bands (140) through encapsulation while permitting the pressure sensor diaphragm (121) to be exposed to ambient pressure without encumbrance or obstruction. Selective encapsulation is made possible by the construction of a protective dam (150) around the outer perimeter of a pressure sensor diaphragm (121) to form a wire bond cavity region between the protective dam (150) and the device housing (105). The wire bond cavity may be encapsulated with an encapsulation gel (160) or by a vent cap (170). Alternatively, the protective dam (150) may be formed by a glass frit pattern (152) bonding a cap wafer (151) to a device wafer (125) and then dicing the two-wafer combination into individual dies with protective dams attached.
